LAMP-HOUSE.

Specification of Letters Patent.

Patented Mar. 1, 1921.

Application filed July 5, 1919. Serial No. 308,694.

To all whom it may concern Be it known that I, Lnwrs A. HOBERDIER, acitizen of the United States, 'residingat Canton, in the county of Starkand State of Ohio, have invented a new and useful Lamp- House, of whichthe following is a specification. I v j The. invention relates toadjusting mechanism for lamp houses and has more especial reference tothe adjusting-mechanism for the lamp and reflector within the lamphouse.

The objects of the present invention are to provide a universallyadjustable lamp carriage and reflector adjusting mechanism; to providean adjusting mechanism which makes the lamp house readily adaptable for.use as a spot light; and to provide a simple and eflicient constructionwhich may be easily and readily operated and quickly adjusted.

With these objects in view the invention consists in the novelconstruction and. ar-

able lamp carriage and the reflector adjust-' ing mechanism.

Fig. 2 is a transverse vertical sectional view through the lamp house.

Fig. 3 is a perspective view of the adjustable lamp carriage.

Fig. 4 is a sectional view of the lamp socket.

Fig. 5 is a rear elevation of a portion of the lamp house showing thereflector adjusting mechanism.

Fig. 6 is a top plan view of the reflector adjusting mechanism showing aportion of the lamp house in section.

Fig. 7 is a detail sectional view of the horizontal adjusting means inthe reflector adjusting mechanism.

Fig. 8 is a longitudinal vertical section through the lamp'house showingthe mechanism adapted for a spot light.

Fig. 9 is a perspective View of a portion of the lamp carriage.

Fig. 10 is a plan view of the reflector adjusting mechanism.

A practical embodiment of the invention is disclosed in the accompanyingdrawings, forming a part of this specification in which similar numeralsof reference indicate corresponding parts throughout the several views.

In Figs. 1 to 7 inclusive are illustrated the lamp carriage and thereflector adjusting mechanism. The lamp is adjustable longitudinally andtransversely in the lamp house in a horizontal plane, and is alsoadjustable vertically. A radial adjustment is also provided upon thelamp socket. A vertical adjustment of the reflector is provided as wellas a horizontal longitudinal adjustment and radial adjustment. I

'A pair of. spaced rods 41 extend longitudinally of the lower portion ofthe lamp house and are carried by the .frame members 42 which are fixedwithin the lamp house. The lamp carriage generally indicated by thenumeral 43 is slidably mounted upon these rods and comprises the endmembers 44 connected by the side rails 45, lugs 46 being provided withsuitable bearings by means of which the carriage is slidably mountedupon the rods 41. A set screw 47 the carriage by meansof a screw 50 orits I equivalent, while the other. end member is pivoted upon the shaft51, said shaft being provided upon its inner end with a pinion 52located within the housing 53 and meshing with the rack bar 54 whichcarries the lamp socket 55; the housing 53 being slidably mounted uponthe rods 49.

The shaft 51 is slidably and rotatably mounted through the adjacent endmember 44 of the carriage and through the sleeve 56 carried by said endmember 44, said sleeve being split at its outer end as shown at 57 andscrew threaded for the purpose of receiving the nut 58 by means of whichthe sleeve may be clamped tightly upon the shaft 51 when the desiredadjustment has been obtained, thus preventing sliding or rotating of theshaft. \Vith the construction above described the lamp, and the tiltingframe thus provided, may be tilted bodily either forward or backward,upon the screw 50 and the rod 51 as pivots.

' The upper end of the rack bar 5% is provided with a disk 59 which islocated between the under surface of the lamp socket and the perforated.disk 60 which is spaced from the lamp socket by means of the washer 61,said washer and disk 60 being attached to the lamp socket by means ofscrews 62 or their equivalents. The disk 59 is thus frictionally heldbetween the under surface of the lamp socket and the perforated disk 60.By this constructionthe lamp socket can thus be adjusted radially uponthe rack bar 5% in order to properly adjust the lamp to bring thefilaments in a plane parallel with the reflector.

The lamp (33 is of any usual and well known construction, suitable foruse in connection with a moving picture machine and is connected to thesocket in the usual manner. A handle 64 is provided upon the socket bymeans of which the socket maybe turned upon the rack bar 54 in order toadj ust the lamp. A bracket 65 is connected to the rear upper portion ofthe lamp house by means of a bolt 66 or its equivalent and is providedwith a horizontally disposed wall 67 through which the screw threadedrod 68 is mounted, said rod being provided with a knob 69 at its upperend; A yoke 70 is carried by the bracket 65. the free ends thereof beingpassed through the bosses 71 which are provided with set screws 72 forfixedly attaching the yoke to the bracket.

The plate 73 is provided with a horizontally disposed portion 74: at itsupper end through which the upper end of the rod 68 is passed. a nut 75being provided upon the lower end of said rod. 1 The plate 73 isprovided with suitable bearings 76 and 77 which are slidably mountedupon the yoke 7 0. The lower end of the yoke is connected to the rearwall of the lamp house by means of a hook 7 8. It will thus be seen thatby rotating the rod 68 the plate 73' maybe vertically moved upon theyoke 7 0.

The tube 7 9 is slidably mounted through a suitable aperture in theplate v '73 and is fixedly connected at its inner extremity to the boss80 which is mounted at the upper extremity of the arm 81 which arm isintegrally formed upon the channel 82. The rack bar 83 is fixedlyconnected to the boss 84 1113011 the channel 82, and passes-through thehousing 85 within which is rotatably mounted the pinion 80, said pinionbeing fixed upon the rod 87, a knob 88 being provided upon the outerextremitypt' the rod for rotating the same.

A rod 89 is rotatably mounted Within the tube 79 and provided with aknob 90 at its outer extremity the inner extremity of said rod beingscrew threaded as shown M91 and located through the nut 92 carried uponthe inner face of the boss 80, said rod being swiveled at its innerextremity to the knuckle 9.3, a link 94 pivotally connecting saidknuckle with the knuckle 95 carried upon the post 96, which post ismounted upon the member 97, pivotally connected lent. 'A pair ofdmvnwardly depending arms 101 are fixedly connected to the member 97 andprovided with hooks 102 at their outer extremities, the reflector 103resting upon said books. A curved wire 104 is connected to the post 96at its lower end and provided with a hook 105 at its upper end whichengages the upper edge of the reflector.

A tube 106 similar to the tube 79 is fixedly connected to the boss 10?carried by the horizontally disposed arm 108 which is formed integrallywith the channel 82. A rod 109 is' rotatably mounted within said tubeand provided with a knob 110 at the outer extremity, the inner endthereof being screw threaded and passed through the nut 111 carried uponthe inner face of the boss 107. The knuckle 112 is swiveled upon theinner end of the rod 109 and is pivotally connected to the arm 113,which arm is rigidly connected to the bearing 99. It will be seen thatthe rear wall of the lamp house is slotted as shown at 11 1 to allow thetubes and rack bar above described to be moved vertically upon the lamphouse.

In Figs. 8 to 10 inclusive is illustrated a modified form of the lampcarriage and reflector adjusting mechanism adaptable for use as a spotlight. Yi ith this construction the reflector adjusting mechanism iscarried upon the lamp carriage thus allowing the reflector and lamp tobe moved together after the reflector has been adjusted withoutchangingthe relative positions of the reflector and lamp.

The lamp carriage proper is of the same construction as that shown inFigs. 1, 2 and 3 with the exception that the rods 41'- upon which thecarriage is slidably mounted ex tend the entire length of the lamphouse, thus allowing greater adjustment of the lamp with reference tothe lens. The casing 53 is provided upon each side with apair of alinedlugs 120 through which. are mounted the screw threaded rods 121, theinverted U shaped member 122 being slidably mounted upon said rods andarranged to be locked in any desired adjustment by :means of a set screw123.

The upper end of the UTSha-ped member 122 is provided with a bearingsocket 124 within which is mounted -the lower extremity of the,post 125,a set screw 126 being provided to lock said 'post in any desiredposition. Upon the upperextremity of the post is carried a casing 127similar in construction to the casing 53, said casing containing apinion mounted upon a shaft 128 provided with an operating knob 129 atits outer extremity. This pinion meshes with the rack bar 130 upon theupper end of which is mounted the channel member 82'.

' The operating rods 91' and 109' and the tubes 79 and 106"within whichsaid rods are mounted/are equivalent to the rods 91 and 109' and thetubes 79and 106 respectively which aretshown in Figs. 1 to 7 inelusiveof the drawings with the exception that in the modified constructionthese rods and tubes are shorter, and the remainder of the reflectoradjusting mechanism is of the same construction as that shoyvn in Figs.1

to 7 inclusive.

For the pn ose ofadapting the construction shown in ig. 8 for use as astereopticon device a horizontal rod 135 is connected to the front wallof the lamp house. A planeconvex lens 136 is mounted upon said rod bymeans of'the lug 137, a set screw 138 holding the lens in position. Thisplano-convex lens, in combination with the plano-convex lens 139 whichis used for the spot light, producing the proper combination of lensesfor use with the stereopticon device. A

stereopticon slide attachment 140 of the same arrangement as the slideattachment 135 is carried upon the frame of the lens 136. The usualstereopticon lens 18 is carried at the forward extremity of the rod 135,being provided with a lug 141 which engages the rod, a set screw 142holding the same in position upon the rod.

When it'is desired to use the device as a spot light, the lenses 136 and18 are swung upwardly upon the rod 135, the lens 139 being used for thespot light and when-it is desired to use thestereopticon device thelenses are swung down in the shown in, Fig. 8. c
